Chael Sonnen tested positive for abnormally high levels of testosterone in his UFC 117 drug screening, California state athletic commission executive director George Dodd told media outlets on Monday afternoon, finally naming the substance that could subject Sonnen to a one-year suspension as well as a fine.
According to Dodd, who spoke to SI.com, Sonnen admitted to him during testing that he had used an illegal performance enhancer prior to the middleweight championship bout against Anderson Silva. Dodd did not name the specific drug Sonnen allegedly admitted to using, and Sonnen did not indicate any usage on a mandatory pre-fight questionnaire.
